Central Heating Installation in the UK: Frequently Asked Questions
How long does a full central heating installation take?
For a 3-bedroom house, expect 3-5 days for a complete installation including boiler, pipework, radiators, and controls. Larger properties or those requiring extensive pipework may take up to 7 days.
What size radiators do I need?
Radiator size depends on room dimensions, insulation level, and window size. Your installer should perform a heat loss calculation for each room. As a rough guide, a typical living room needs 1,500-2,000 BTUs per square metre.
Should I get a combi or system boiler?
Combi boilers are ideal for smaller homes (1-3 beds, 1 bathroom) as they heat water on demand. System boilers suit larger homes with multiple bathrooms, using a hot water cylinder for better flow to multiple taps simultaneously.
